Git4Voc: Git-based Versioning for Collaborative Vocabulary Development

Collaborative vocabulary development in the context of data integration is the process of finding consensus between the experts of the different systems and domains. The complexity of this process is increased with the number of involved people, the variety of the systems to be integrated and the dynamics of their domain. In this paper we advocate that the realization of a powerful version control system is the heart of the problem. Driven by this idea and the success of Git in the context of software development, we investigate the applicability of Git for collaborative vocabulary development. Even though vocabulary development and software development have much more similarities than differences there are still important differences. These need to be considered within the development of a successful versioning and collaboration system for vocabulary development. Therefore, this paper starts by presenting the challenges we were faced with during the creation of vocabularies collaboratively and discusses its distinction to software development. Based on these insights we propose Git4Voc which comprises guidelines how Git can be adopted to vocabulary development. Finally, we demonstrate how Git hooks can be implemented to go beyond the plain functionality of Git by realizing vocabulary-specific features like syntactic validation and semantic diffs

Democratic Education In The Egyptian Higher Education: Investigation Of Tutors’ Perception Of Democratic Education In The Egyptian Higher Education

Democratic education (DE) sees young people not as passive recipients of knowledge, but rather as active co-creators of their own learning and valued participants in a learning community. This study investigates tutors’ understanding and implementation of DE in the Egyptian Higher Education (HE). It investigates HE tutors’ conception about learners controlling their educational process by being fully embedded in it. Data for this qualitative paper was collected from 20 tutors from two Egyptian universities via one-to-one interviews and focus groups. This study highlighted the inference of political events in Egypt, since 2011, on HE students in their way of thinking and reflecting and addressed the need of DE to be a part of the educational paradigm. This paper concluded that DE is based on placing students in the centre of their learning and empowering them. Also, tutor-student dialogic approach and tutor-student trust are essential approaches to implement DE

Mobility in higher education: new need to improve it?

The aim of The Bologna Process is, amongst others, to improve the mobility of students in Higher Education. The Erasmus programme helps students to study in other European Universities, know other countries, live another culture (folklore, food, language, etc.), develop autonomy and mature as an adult person. In Cadiz, Spain, the international seminar “Improving mobility through collaborative exchange” took place in May 2015. The participants were universities of Glasgow (UK), Madeira (Portugal), Gazi (Turkey), Linz (Austria), Zielona Gora (Poland) and Cadiz (Spain). Representatives from those countries expressed concern about problems that students might suffer during mobility. The literature has pointed out that the economic, social and academic stresses they experience can, in some cases, generate or exacerbate mental disorders (Bradley, 2000) and generate depression and anxiety (Russell et al, 2010; Ying & Han, 2006) which can even manifest itself in somatic symptoms (Mori, 2000); this could involve classroom absences and drug taking as side effects.This study describes the positive experiences of five University of Cadiz Erasmus students under a collaborative exchange between the universities, detailing the measures taken by the host universities to address potential stressful issues

Creativity and innovation in science and technology: Bridging the gap between secondary and tertiary levels of education

Purpose: This paper stems from a study which was conducted as a means to first, find out whether there is a gap between the secondary and tertiary education levels, second identify any existing gap in Science and Technology education, and third, examine the impact of the above upon students’ creativity and innovativeness at university level. The paper aims to discuss these issues. Design/methodology/approach: As such, a group of teachers and students at both secondary and tertiary levels were selected as the sample of the study. Questionnaires were administered to trained secondary school teachers and to university students. Interviews were also conducted to triangulate data. These enabled an analysis of the current situation in terms of students’ engagement/creativity/innovativeness in Science and Technology at secondary and tertiary levels. Findings: The findings reveal a problematic situation arising with respect to beliefs and what truly prevails in the education sector at secondary and tertiary levels. This study has revealed a number of salient issues related to the gap existing between the secondary and tertiary levels of education in Mauritius, with special bearing on creativity and innovation in Science and Technology. Research limitations/implications: Only three institutions were involved, with a small sample of students, so that the findings cannot be generalised. Moreover, gender is a variable that has not been taken into consideration. Practical implications: The study has proposed a number of recommendations to enable Mauritian students (at secondary and tertiary levels) to develop creativity and hopefully become innovators. This leads us to believe that the recommendations emerging from this study will be beneficial to various stakeholders who wish to understand the gap existing between secondary and tertiary education in Science and Technology education. Originality/value: This study takes a case study approach adopting a mixture of interviews, surveys and observations to understand the research problems with regards to the younger generations need to be equipped with scientific and technological advances in acquiring knowledge, new sets of skills and values. Therefore, this study endeavours to document the perceptions of learners and faculty staff

Sequential Selection of Correlated Ads by POMDPs

Online advertising has become a key source of revenue for both web search engines and online publishers. For them, the ability of allocating right ads to right webpages is critical because any mismatched ads would not only harm web users' satisfactions but also lower the ad income. In this paper, we study how online publishers could optimally select ads to maximize their ad incomes over time. The conventional offline, content-based matching between webpages and ads is a fine start but cannot solve the problem completely because good matching does not necessarily lead to good payoff. Moreover, with the limited display impressions, we need to balance the need of selecting ads to learn true ad payoffs (exploration) with that of allocating ads to generate high immediate payoffs based on the current belief (exploitation). In this paper, we address the problem by employing Partially observable Markov decision processes (POMDPs) and discuss how to utilize the correlation of ads to improve the efficiency of the exploration and increase ad incomes in a long run. Our mathematical derivation shows that the belief states of correlated ads can be naturally updated using a formula similar to collaborative filtering. To test our model, a real world ad dataset from a major search engine is collected and categorized. Experimenting over the data, we provide an analyse of the effect of the underlying parameters, and demonstrate that our algorithms significantly outperform other strong baselines
